City Hall – DR assigned this issue to Police - JW (Communications)

Bikes are allowed on Rindge Avenue. The only roads they are not allowed on are limited access highways. That doesn't mean it's ok for cyclists to weave in and out of traffic or fail to signal lane changes. Of course, if individual cyclists don't feel confident riding in heavy traffic they should stick to the sidewalk and common sense should tell them that on a narrow sidewalk like the one next to Rindge Ave they should walk their bikes.

Somehow i doubt people on bikes are putting anyone in danger

Thanks for your sharing your concerns, Pat. Only in banned areas are bicyclists required to walk their bike. A map of those areas can be found at http://www.cambridgema.gov/CDD/Transportation/gettingaroundcambridge/bybike/rulesoftheroad.
